Seat heaters in the test (2019) – AUTO BILD

Winner in the AUTO BILD seat heating test: Mobicool Mh40 S
The test winner Mobicool MH40 S impresses with its good workmanship and comfortable upholstery with lumbar support – a real upgrade for the car seat. In the test, the edition from Mobicool received the grade “very good”.
Price-performance winner OK Cars seat cover with heating
Good product at an affordable price: The seat cover with heating from OK Cars convinces with good heating performance, solid attachment and decent padding. The very bright LED (can dazzle) is more of a complaint at a high level. Especially since the OK Cars edition is hot on the heels of the test winner with a final grade of “good +”.
How AUTO BILD tested it

The temperature profile was measured with several thermometers and a dummy.
A dummy on the seat cushion, thermometer on the backrest and seat surface: Then, at certain time intervals, how quickly the cushions heat up was measured. The seat cover should warm up to temperature as quickly as possible and keep it there. The test editors then sat down themselves and incorporated the subjective impression. It was also evaluated how comfortable the pad is in terms of shape, padding and additional features. The installation and connection was evaluated in the “Operation” chapter.

Seat heating for retrofitting
The test results at a glance
Unfortunately, the most expensive model (Klingleting) is disappointing as soon as it is unpacked: the support is only 30 centimeters wide. At best, one buttock gets warm – the comparatively high-quality leather cover hardly makes up for that. The APA seat pad is wide enough, but stays cold at the edges. And the support of HP car accessories only reaches 25 degrees in our measurements. The heating mats from Ok Cars and Dometic (Mobicool) show that there is a better way: They heat up quickly and distribute the heat evenly. The Lescars pad is a safety risk: The rubber straps for attachment can affect the side airbag when it is triggered – a shortcoming in terms of safety, which is why it is only enough for the last seat here.
Conclusion on the seat heating test
The seat cushions for retrofitting are not a feast for the eyes, but in winter warmth is important – and it is available here quickly and reliably. Tip: Keep an eye on the side airbags when installing!
What should you pay attention to when using a heated seat cover?
Fit: The heating mat must fit well in the car seat and should not slip if possible. It should also be wide enough to ensure an even supply of heat.
Airbags on the seat: If the seat has side airbags, these should not be covered by belts or elastics, otherwise they could impair deployment.
Comfort: If you value comfort, you should pay attention to good padding. In addition, some seat cushions offer different heating levels.
